A new apparatus for measuring rate constants and activation energies of thermal electron capture processes in the gas phase

The new apparatus for investigation of kinetics of a thermal electron capture process and its temperature dependence with pulsed Townsend technique has been built. This method gives straightforward results on electron drift velocities in any mixture and allows calculating the rate constants for electron capture as well as activation energies of this process. The thermal electron capture rate constants and activation energies for CH3CCl3, CHCl2CH2Cl and CH3CHClCH2CH3 have been determined.
